Effect of annealing on magnetic property-structure/microstructure correlation in nanostructured ribbons of a rare-earth-free Hf1.5Zr0.5Co10FeB alloy has been reported in the present study. Melt-spinning of the arc melted alloy was employed to obtain the ribbons. The compositional, structural and magnetic measurements demonstrate that under optimized annealing conditions, the magnetically hard phases Hf2Co11B and ZrCo5.1 appear as the dominant ones, while the magnetically soft phases Zr6Co23 and cubic Co appear as minor phase. The optimally annealed ribbons show promising values for characteristic magnetic parameters such as the saturation magnetization M-s similar to 76.7 emu g(-1), intrinsic coercivity H-i(c) similar to 2.4 kOe and magnetic energy product (BH)(max) similar to 4 MGOe. Processing steps like magnetic alignment and magnetization would further improve the characteristic parameters.
